MCG unveils new all terrain, cab, luffing tower

Announced at the Intermat exhibition in Paris last month by Manitowoc Crane Group was a new 100 tonne Grove all terrain crane, the four axle GMK4100 (GMK4115 in the US). Deliveries are due to start in August.

It has a 52 m six-section Megaform boom with the Twin-Lock pinning system. A 10 to 17 m bi- fold swing away jib can specified as can two additional 5 m inserts to give a maximum tip height of 82 m. Preliminary charts show it will pick 17 tonnes at 10 m radius with 40 m of boom and 21.7 tonnes of counterweight, while with 6.3 tonnes of counterweight it will pick 13.6 tonnes, both through 360 degrees. Powering the superstructure is a 110 kW (147.5 hp) Mercedes- Benz OM 904 LA diesel.

On the carrier, standard is 8 x 6 x 8 drive/steer with independent rear and crab steering and 8 x 8 x 8 is optional. Power is from a 295 kW (390 hp) Mercedes-Benz engine driving through a Mercedes G240-16 transmission with 16 forward and two reverse gears and two stage transfer case. The GMK4100 is under 12 tonnes per axle on 16.00 R25 tyres with 6.3 tonnes of counterweight, swing away jib and 16 tonne hook block. Up to 26.1 tonne of counterweight can be carried.

Also unveiled at Intermat was a new carrier cabin that will debut on the new GMK4100. Based on technology from the commercial vehicle industry, the new cab has an emphasis on operator comfort and has a streamlined form to reduce fuel consumption, among other benefits. Customers and distributors had input on the new design, which is presented as an example of the company's “innovation for productivity” approach.

The new cabin will be fitted to GMK series all terrains with up to four axles. Another new cabin is under development for larger models, said Frans Vanwinkel, MCG vice president, sales and marketing, EMEA.

Also announced at Intermat was the Potain MR 295 luffing jib tower crane, announced in IC January and available in three versions. Lifting capacity is up to 25 tonnes and maximum radius is 60 m where 2.8 tonnes can be lifted.
